Data is collected during operation of a vehicle. A determination is made that a confidence assessment of at least one of the data indicates at least one fault condition. A first autonomous operation affected by the fault condition is discontinued, where a second autonomous operation that is unaffected by the fault condition is continued.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A system, comprising a computer in a first vehicle, the computer comprising a processor and a memory, wherein the computer includes instructions to: collect data during operation of the first vehicle; determine that a confidence assessment of at least one of the data indicates at least one fault condition in at least one data-providing component in the first vehicle; transmit a communication to at least one second vehicle indicating the at least one fault condition; and receive at least one datum from a second vehicle; determine an autonomous operation of the first vehicle based at least in part on the at least one datum.
2. The system of claim 1 , wherein the autonomous operation is one of maintaining a lane in a roadway, maintaining a speed, pulling to a side of a roadway, and bringing the first vehicle to a stop.
3. The system of claim 1 , wherein the communication includes data sent according to Dedicated Short Range Communications (DSRC).
4. The system of claim 1 , wherein the communication is made using visual light emitted by the first vehicle.
5. The system of claim 1 , wherein the computer further includes instructions to use the at least one datum to determine a location of an obstacle.
6. The system of claim 1 , wherein the at least one datum includes at least one of a location of the second vehicle, a location of an object on a roadway, a location of a lean on a roadway, a location of a third vehicle, and an instruction for operating the first vehicle.
7. The system of claim 1 , wherein the at least one fault condition is related to at least one of a sensor in a first vehicle and a reliability of a data value determined in the first vehicle.
8. A system, comprising a computer in a vehicle, the computer comprising a processor and a memory, wherein the computer includes instructions to: collect data during operation of the first vehicle; determine that a confidence assessment of at least one of the data indicates at least one fault condition in at least one data-providing component in the first vehicle; and discontinue a first autonomous operation affected by the fault condition; continue a second autonomous operation that is unaffected by the fault condition.
9. The system of claim 8 , wherein at least one of the first autonomous operation and the second autonomous operation is one of maintaining a lane in a roadway, maintaining a speed, pulling to a side of a roadway, and bringing the first vehicle to a stop.
10. The system of claim 8 , wherein the computer further includes instructions to use the at least one datum to determine a location of an obstacle.
11. The system of claim 8 , wherein the at least one datum includes at least one of a location of the second vehicle, a location of an object on a roadway, a location of a lean on a roadway, a location of a third vehicle, and an instruction for operating the first vehicle.
12. The system of claim 8 , wherein the at least one fault condition is related to at least one of a sensor in a first vehicle and a reliability of a data value determined in the first vehicle.
13. A method, comprising: collecting, in a first vehicle computer, data during operation of the first vehicle; determining in the first vehicle computer that a confidence assessment of at least one of the data indicates at least one fault condition; causing, by the first vehicle computer, transmission of a communication to at least one second vehicle indicating the at least one fault condition in at least one data-providing component in the first vehicle; and receiving in the first vehicle computer at least one datum from the at least one second vehicle; determining an autonomous operation of the first vehicle based at least in part on the at least one datum.
14. The method of claim 13 , wherein the autonomous operation is one of maintaining a lane in a roadway, maintaining a speed, pulling to a side of a roadway, and bringing the first vehicle to a stop.
15. The method of claim 13 , wherein the communication includes data sent according to Dedicated Short Range Communications (DSRC).
16. The method of claim 13 , wherein the communication is made using visual light emitted by the first vehicle.
17. The method of claim 13 , further comprising using the at least one datum to determine a location of an obstacle.
18. The method of claim 13 , wherein the at least one datum includes at least one of a location of the second vehicle, a location of an object on a roadway, a location of a lean on a roadway, a location of a third vehicle, and an instruction for operating the first vehicle.
19. The method of claim 13 , wherein the at least one fault condition is related to at least one of a sensor in a first vehicle and a reliability of a data value determined in the first vehicle.
20. The method of claim 8 , wherein the confidence assessment includes determining a confidence interval in a set of confidence intervals into which a confidence value falls.
